Schaeht, 205 E. 63rd St., New York, N.Y. 10021 Filed June 7, 1966, Ser. No. 555,892 Claims. (Cl. 49-253) ABSTRACT OF THE DISCLOSURE This invention relates to closures and especially to window easements wherein the sash may be swung out from its frame and rotated so as to permit manual access to the normal outer or weather face of the sash from within the building.

Window easements are customarily of either of two types. Of the first type are those wherein the sash is piv' otally mounted on a vertical axis within the frame. When rotated, half of the window swings into the building. The weather-proofing seals are customarily of the wiping type. Such windows preclude the normal usage of the area within the building within the radius of the window, and suffer from rapid deterioration of the weatherproofing seals, particularly at the corners where the seals have to flex in two directions. Of the second type are those wherein the sash is pivotally mounted on a vertical axis from arms, which arms are pivotally mounted on a vertical axis within the frame. When rotated, the window swings either into or away from the building on its arms, and may be rotated within its arms. If the Window swings inwardly, it precludes the normal usage of the area within the radius of the window. If it swings outwardly, it is subject to the effects of the wind in the same manner as a sail. If the window is large, such as in modern, nonresidental buildings, the force on the window provided by even a light wind may be manually unmanageable. Any lack of parallelism between the supporting arms, may cause a springing of the sash. The weather-proofing seals may be made of the compression type. A window of this type was early taught in US. Patent No. 652,216, issued June 19, 1900.

Accordingly, it is an object of this invention to provide a casement window, having a sash pivotally supported by outwardly swinging arms, to provide access to the weather face of the sash from the interior of the building, with excellent weather-proofing, wind control, nonspringing and esthetic characteristics.

A feature of this invention is the provision of a casement window having a sash pivotally supported on a vertical axis in an integral arm support, which support is pivotally mounted for limited rotation to provide access from the interior of the building to the weather side of the sash, most of the integral arm support being concealed from view, with means for fully compressing the weather-proofing seals around the sash when the window is closed.

These and other objects, features and advantages of this invention will be apparent from the following specification taken in conjunction with the accompanying drawings in which:

The embodiment of the invention herein illustrated comprises a window casement having a frame 10 which is fixed within the building wall 12, an integral arm support 14 which is pivotally mounted to the frame, and a sash 16 which is pivotally mounted to the support.

The frame 10 may be bent out of sheet metal to provide a stepped cross-section having a lock or hinge remote jamb 18, with a weather lateral face 20, a cross face 22, a lateral face 24, a cross face 26, a seal lateral face 28, a cross face 30 and an interior lateral face 32. The frame also has a hinge jamb 34, a header 36 and a sill 38. The hinge jamb has a weather lateral face 40, a cross face 42, a seal lateral face 44, a cross face 46; and an interior lateral face 48. The header and the sill are similar and each has a weather lateral face 50, a cross face 52, a seal face 54, a cross face 56, and an interior lateral face 58.

The sash 16 may be bent out of sheet metal to provide four sides each having a central beam 60, a U channel 62 for receiving a pane of glass 64, and a C channel 66 for receiving a length of resilient sealing material 68.

The integral arm support 14 comprises a vertical shaft 70 having an upper and a lower portion 72, which may be of reduced diameter. An upper and a lower arm 74 each have a bore 76 therethrough, adjacent one end, through which bore a respective portion 72 is disposed and secured, as by welding. An upper and a lower hearing block 78 are respectively secured, as by screws 80, to the cross faces 52 of the header and the sill adjacent the hinge jamb. Each block 78 has a bore 80 therethrough, through which bore a respective portion 72 is disposed with freedom to rotate. A thrust washer 82 is respectively disposed over the projection 72 between the confronting surfaces of the arm and the block. The block 78 may be cut out at 84 to receive a projecting lip 86 which conceals most of the block 78 when the window is closed. Each arm 74 has a stepped bore 88 adjacent the other end, through which bore is fixed a respective stepped pivot 90. The reduced end 92 of the pivot passes through a thrust washer 94 into a bore 96 in the beam 60 of the sash. The two pivots 90, the two arms 74 and the shaft 70 are integral. The central axes of the two pivots 90 are coaxial and parallel to the central axis of the shaft 70.

A U shaped cover 98 is secured, over the shaft 70, to the seal face 44, by suitable means, such as rivets 100. A shield 102., which may be L shaped, having a lateral leg 104, is secured to the cross face 42, 'by suitable means, such as screws 106. The ends of the leg 3 1% are cut out at 198 to clear the arm 74 for rotation and to provide a surface 110 to abut the weather face of the arm 74 and to limit its maximum rotation with respect to the window frame.

A skirt 112 is respectively fixed to the upper and lower surfaces of the sash, by any suitable means, up to the ends of the arms 74 to shield the gap between the sash and the surface 52 where the block 78 is absent, and to provide a respective surface 114 to abut the weather face of the respective arm 74 to thereby limit the maximum rotation of the sash with respect to the support arms.

It will be appreciated that by permitting the sash to rotate with respect to the arms as the arms are rotating with respect to the frame, the hinge edge of the sash may be brought quite close to the edge of the shield leg 104. In fact, the shield is here shown as made to overlap the weather face of the sash, and will act as a fulcrum for the sash to compress the weather stripping tightly when the edge of the sash is initially tucked between the shield leg 104 and the seal face 44, and the sash is subsequently fully closed.

In an exemplary window casement, the following dimensions, which are not to be taken as limitative, are used. The overall width of the sash, from outer edge to outer edge is 2'4". The radius of the arm '74 between the central axes of the shaft 7%) and the pivots 90 is 10". The distance between the central axis of the shaft 70 and the weather face of the shield leg 104 is 'Ms. The height of the sash is 7'8".

A latch or lock 116 is provided between the lock jamb 18 and the adjacent hinge remote side of the sash. The latch has a lever with a cam on the sash and a cam follower on the jamb to permit a tight closing of the sash and compression of the weather seals 68.

The stop edge 110 is suitably spaced with respect to the arms 74 so as to preclude a shifting of the hinge remote edge of the sash beyond comfortable manual reach when the window is opened and the weather face of the sash is swung inwardly. The stop edge 114 is suitably spaced with respect to the arm 70 so as to preclude the abutment of the hinge remote edge of the sash with the weather face of the building. When the window is opened and the weather face of the sash is swung inwardly, the pivot 90 is made as close to one half the width of the sash as is consistent with convenient manual reaching of the Weather face of the sash when it is rotated. It is desirable to locate the pivot relatively close to the middle of the width of the pivot so as to approach a balance of the areas of the sash about its pivot, and thus to minimize any tendency of the wind to swing the sash about its pivots. The stops 110 and 114 serve the additional function of limiting the sash when it is opened to a maximum position which is substantially parallel to the weather face of the building. Thus, should a wind blowing parallel to the weather face of the building blow the sash and the supporting arm structure about the shaft 70, its effect will be minimized at maximum swing since the wind will be blowing at the sash edge on.

It will be appreciated that when the window is closed the sash compresses the weather stripping uniformly against the seal faces of the frame, ensuring a weather tight seal. During opening and closing of the sash there is no uneven wear of the weather stripping. The shield eg 104 protects the shaft recess from the accumulation of foreign matter such as dirt or snow.

While I have shown and described the preferred embodiment of the invention, it will be understood that the invention may be embodied otherwise than as herein specifically illustrated or described, and that certain changes in the form and arrangement of parts and in the specific manner of practicing the invention may be made without departing from the underlying idea or principles of this invention within the scope of the appended claims.
